Actually you not only can but you MUST blame it on the customers when they’re deliberately shrinking their bill AND your profit.

Because the customer offered himself the "all you can eat" deal?

A business owner who offers the "all you can eat" deal has no responsibility when someone takes them up on it???

Yeah he has the responsibility to kick them out before they bankrupt him. All you can year relies on the social contract of people not making a spectacle of themselves. When you get people that can’t handle that you kick them out.
